/Patch 3.0.2 (14-Oct-2008): This aura is now raid-wide and now increases all ranged and melee attack power by 10%. In addition, this spell now only has one rank. All other ranks have been removed. Old - party-wide buff.

Patch 2.3.0 (13-Nov-2007): No longer costs mana to cast and will last until canceled. Previously required a sizable chunk of mana to cast, making it expensive to turn on in combat if it was forgotten previously.
